9 Claims. (Cl. 260-937) This application is a division of application 245,976, filed December 20, 1962, now US. Patent No. 3,206,474.

This application is a continuation-in-part of application 214,508, filed August 3, 1962, now US. Patent No. 3,096,345.

The present invention relates to novel phosphonates.

It is an object of the present invention to prepare phosphonates of polyhydric alcohols having at least three hydroxyl groups.

Another object is to prepare novelheterocyclic acetal and ketal phosphonates.

A further object is to prepare novel phosphonates by the hydrolysis of acetal and ketal phosphonates.

A still further object is to prepare novel open chain acetal and ketal phosphonates.

Still further objects and the entire scope of applicability of the present invention will become apparent from the detailed description given hereinafter; itshould be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention are given by way of illustration only, since .various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

It has now been found that these, objects can be attained by preparing novel acetals and ketals having one of the formulae- R7I L OR where R; is alkyl, alkenyl, aralkyl or R R is alkyl, alkenyl, aralkyl, aryL'haloaryl or R and R is where R is hydrogen alkyl, aryl, haloaryl or nitroaryl, R is hydrogen, alkyl aryl, haloaryl or nitroaryl; or

is an alicyclic, i.e. a cycloalkyl group, R is hydrogen, alkylor aryl, R is hydrogen or alkyl, R is hydrogen or alkyl, RA is hydrogen, or lower alkyl, e.g., methyl or ethyl, v is 0 or an integer, e.g., from 1 to 100, n is an integer between 1 and 10, m is 1 or 2;

ii/ Bur-P Patented June 21', 1966 where R is alkyl, alkenyl or aralkyl and R and R are as defined above R11O R2 OR:

(111) where R is alkyl, alkenyl aryl, haloaryl or aralkyl and R R and R are as defined above 1 f R10-1|-0(CH2CHO)r-OOHflOHOCOCHQHO(QHzCH)Ox:F'-R1o Rn-O g ORuwhere R R R R R are as definedabove, and x is an integer of at least 1', e.g;, from 1 to 100.

There are also included phosphonates ofdiacetals and ketals or hexitols such as sorbitol and mannitol. Typical of such materials are compounds having the formula where R R and R are as defined above.

In Formula V no attempt has been made to show the position of the hydrogen atoms on the asymmetric carbon atoms.

also can be varied so long'as there are two such groups in the molecule.

The compounds of the present invention are useful.

as waterdispersible wetting and suspending agents They can also be employed as fire retardants for cellulose, cellulose esters, e.g. cellulose acetate, polyolefin resins, e.g. polyethylene and polypropylene.

A particular important use for the acetals and ketals of the present invention is to hydrolyze them to give hydroxyl containing phosphonates. Such hydroxyl containing phosphonates have the following formulae i R7VIILOR13, Biz-O where R, is as defined above, R is alkyl, alkenyl, aralkyl, aryl, haloaryl or R and R as where R is as defined above.

Theposition of the acetal and ketal groups.

The hydrolyzed phosphonates, ie the compounds of Formulae VI, VII, and VIII, have the uses set forth supra and in addition are useful for preparing polyurethanes by reaction with organic isocyanates, e.g. toluene diisocyanate and PAPI (polyphenylene isocyanate averaging about 3 units in the polymer). The polyurethanes can 'be prepared as foams or as elastomers. The presence of the phosphonate group renders the polyurethane flame resistant. The phosphonate need-be used only as a portion of the polyols employed. Thus, the use of 20% of a polyhydroxyl containing phosphonate according to the present and 80% of another polyol, e.g. glycerine propylene oxide adduct molecular weight 3000 or polypropylene glycol 2025 will give a polyurethane with with improved flame resistance.

The novel compounds of Formulae I through V of the present invention are prepared by Arbuzov rearrangement of the corresponding phosphite prepared according to the parent application.

Thus, there is employed an alkyl halide, alkenyl halide, aralkyl halide, halohydrin or epihalohydrin with a phosphite of the parent application that is isomeric with a phosphonate of Formulae I through V above. The iodides and bromides are preferred although there can also be employed the chlorides. The halides can be employed in catalytic amounts, e.g. 0.5-5 mol percent based on the phosphite to be rearranged. If the hydrocarbon group of the halide is the same as one of the esterifying groups of the phosphite, then no impurities are introduced into the phosphonate product. By employing a large amount of the halide, e.g. 80 mol percent, or preferably 100 mol percent or more, based on the phosphite employed in.the Arbuzov reaction, then the product is one in which one of the esterifying groups on the phosphorus atom is removed and the phosphorus atom is directly attached to the hydrocarbon, hydroxyhydrocarbon or epoxyhydrocarbon group of the halide employed. When one of the esterifying groups of the phosphite is aryl or haloaryl, suflicient alkyl halide or the like must be used to replace the aryl or haloaryl group since aryl halides do not normally take part in the Arbuzov reaction. The Arbuzov reaction is usually carried out at elevated temperatures, e.g. 120200 C. at atmospheric, subatmospheric or superatmospheric pressure. The halide remaining after the reaction can normally be removed by distillation.

Among the halides which are employed in the Arbuzov reaction are methyl bromide, methyl iodide, ethyl bromide, ethyl iodide, n-propyl iodide, isopropyl iodide, amyl bromide, amyl chloride, amyl iodide, butyl bromide, hexyl iodide, octyl bromide, octyl iodide, decyl bromide, decyl iodide, dodecyl iodide, octadecyl bromide, octadecyl iodide, allyl bromide, allyl iodide, allyl chloride, methallyl iodide, crotyl bromide, vinyl bromide, oleyl bromide, oleyl iodide, b-enzyl chloride, 'benzyl bromide, :benzyl iodide, o-dodecylbenzyl chloride, p-dodecylbenzyl chloride, m-dodecylbenzyl chloride, p-dodecylbenzyl bromide, epichlorhydrin, epibromohydrin, epiiodohydrin, ethylene chlorhydrin, ethylene bromohydrin, ethylene iodohydrin, propylene chlorhydrin, propylene bromohydrin.

The compounds of Formulae VI through VIII are prepared by hydrolysis of the compounds of Formulae I, II, and V. The hydrolysis is carried out with the aid of water, preferably with heating, e.g. up to 100 C The reaction mixture is usually slightly acidic due to the starting phosphonate. After hydrolysis is completed, an alkaline material, e.g. sodium hydroxide, sodium carbonate,sodium bicarbonate or potassium hydroxide is added to neutralize the product.

Example 9 200 grams of the methyl bis (4-(2-methyl-2-ethyl-1,3- dioxacyclopentyl)butyl) phosphite (the ketal phosphite prepared in Example 5) was heated for 7 hours at 140 C. with one gram of ethyl iodide as a catalyst. The conversion to phosphonate was followed by periodic sampling and titration with 0.1 N iodine in benzene during the heating period. All of the phosphite was converted after the 7 hours of heating. After vacuum stripping, there was obtained as the product in a yield of 99.4% bis (4 (2 methyl-Z-ethyl-1,3-dioxacyclopentyl) 21 butyl) methylphosphonate as a colorless liquid having the structure:

The pH of the mixture Was between 2 and 4 due to a small residual acidity of the ketal phosphonate. By the end of the heating period, the reaction mixture was homogeneous due to hydrolysis of the ketal groups. There was no change in acidity indicating no hydrolysis of the phosphonate to phosphonic acid. The reaction mixture was cooled, neutralized to a pH of 7 with sodium hydroxide and the water was removed in vacuo.
